Before a novel material enters production, its deposition, etching, removal, and compatibility with adjacent layers must be researched.

“Um, the answer is slightly different when you're dealing with an architecture like CFET versus a novel material. Uh, materials have, of course, the challenges of, uh, being deposited, etched, removed, uh, their compatibility with other layers above and below.”

“All those things have to be researched first before you put them in a production line. Uh, an architecture may seem like a simple evolution. Oh, you're making nanoribbon transistors next to each other.”
